目的探讨CT对肝癌TACE术后疗 效以及残灶活性的评估作用，为今后临床 实践提供参考和借鉴，以提高对肝癌TACE 术后疗效方面的诊断水平。方法 选择我 院收治的68例经临床确诊并行经导管动脉 栓塞术治疗的肝癌患者为研究对象，行肝 癌TACE治疗后1-3月对其进行CT、DSA复 查，探讨CT对肝癌TACE术后疗效以及残灶 活性的诊断价值。结果 CT检查结果与DSA 检查结果相比，p＞0.05，差异没有统计 学意义；CT诊断敏感性、特异性、准确率 与DSA检查相比，p＞0.05，差异没有统计 学意义。结论 CT对评估肝癌TACE术后疗 效方面及残灶活性方面具有重要价值，其 影像具有一定的特征性，对TACE治疗后肿 瘤残存的检测敏感性、准备率比较高，能 够为预测治疗效果及判断生存预后等方面 提供较多的信息，为患者的后续治疗提供 依据，具有较高的临床使用价值。

Objective to investigate the evaluation effect on postoperative efficacy of Computed Tomography (CT) after liver cancer TACE surgery and its diagnositic value on the activity of residual lesions, and to provide the reference for clinical practice in the future in order to improve the diagnositic level of postoperative efficacy after liver cancer TACE surgeries. Methods 68 liver cancer patients undergone transcatheter arterial chemoembolization (TACE) were selected as the research object, and they were given the CT examination in 1 to 3 months after surgery, and finally the effect on postoperative efficacy of CT after liver cancer TACE surgery and its diagnositic value on the activity of residual lesions were explored. Results The comparison between examination results of CT and that of DSA was analyzed, the difference was not statistically significant(p>0.05). The differences in diagnostic sensitivity, specificity and accuracy of CTand that of DSA examination were not statistically significant(p>0.05). Conclusions CT has important diagnositic value on the evaluation of postoperative efficacy of liver cancer and the activity of residual lesions. The images are of certain characteristics, the detection sensitivity and preparation rate are considerable on tumor residues after the treatment of TACE, and it is able to provide more information for predicting the treatment efficacy and judging prognosis of survival and to provide the basis of subsequent treatment of patients.
